Rework 7b2b1190 so that it is more aligned with others spring
application events. Fix the package tangle by moving the publication part
to EventPublishingRunListener.

Previously, a TransportClient sniff property could not be configured
while using Spring Boot’s Elasticsearch auto-configuration. This commit
adds a new property, spring.data.elasticsearch.client-transport-sniff,
that can be used to configure the TransportClient while continuing to
use the auto-configuration support.

* gh-2375:
  add spring-boot-sample-activemq

The actual required Spring Framework version is 4.1.5.

See gh-2575

The example `@Value("server.local.port")` should read
`@Value("${local.server.port}")`.

Fixes gh-2628

Update HealthIndicatorAutoConfiguration to reduce the amount of
duplication in inner configuration classes.

Closes gh-2662

In ActiveMQ 5.11 the signature of
PooledConnectionFactory.setConnectionFactory has changed. It now takes
an Object rather than a ConnectionFactory. This change is not binary
backwards compatible so it causes a NoSuchMethodError as we compile
against 5.10.

This commit updates ActiveMQConnectionFactoryConfiguration to call
the setConnectionFactory method reflectively, looking for both the
ConnectionFactory and Object variants.

Closes gh-2640

Closes gh-2647

PropertySourcePropertyValues tries to process a PropertySource first
as an EnumerablePropertySource and then as a CompositePropertySource.
In Spring 4.1.2 CompositePropertySource was updated to extend
EnumerablePropertySource. This change meant that a
CompositePropertySource would always be processed as an
EnumerablePropertySource.

This commit updates PropertySourcePropertyValues to process a
PropertySource as a CompositePropertySource first and to then try it
is an EnumerablePropertySource.

Fixes gh-2608

Unfortunately it still has to happen in a @PostConstruct (otherwise
JPA never sees the schema in time), but we can delay a bit by not
using @Autowired. Appears to fix the Spring Cloud problem
(https://github.com/spring-cloud/spring-cloud-config/issues/105).

Fixes gh-2658

Add `create` as a valid values for `spring.jpa.hibernate.ddl-auto`

Fixes gh-2641

Add an event that indicates the Spring Application has fully started and
is now ready to service requests. While ContextRefreshEvent provides
such hook for a regular spring application, this dedicated event is
triggered once all callbacks have been processed and right before the
context is returned to the caller. Besides, such event is triggered once
per application, regardless of the number of (child) contexts that could
have been created.

Closes gh-2638

Define an additional health indicator for each ConnectionFactory instance
defined in the context. Extracts the provider name from the connection
meta-data.

Fixes gh-2016

  Add mail health check

Define an additional health indicator for each JavaMailSenderImpl
instance in the context.
